Raise to Speak not available on Series 2

I have not seen the option to enable it on S2 on any of the betas. I also haven't been able to confirm or deny that Raise feature is, or is not, going to function on S2. Usually when a feature won't work on certain devices, they clearly state which models support certain features and which don't.

Seeing the same thing here on my series 2.

Same here... no raise to speak on my Series 2

Yea, I guess it's a hardware limitation, my Series 1 doesn't show this feature as well. They might change this in a future update but the betas are a very late state so I don't think that this will change.

Only for series 3 or later, :-(
